[0002] Flue-cured tobacco thermal cycle drying is a tobacco leaf drying technology that removes moisture from tobacco leaves by heating and circulating air to make the tobacco leaves reach a certain degree of dryness. This technology can improve the quality and taste of tobacco leaves, making them more suitable for processing and sales.

[0003] A Chinese patent discloses an intensive flue-cured tobacco thermal circulation drying device (authorization announcement number CN218418368U). This patented technology hangs bundles of tobacco leaves on hooks, then turns on a hot air blower, which generates hot air. The hot air passes through a central drying column and is sprayed outward from a hot air port to dry the tobacco leaves hung on the hooks. The hot air then re-enters the hot air blower through an air collecting trough and a connecting trough for heating and drying. The hot air inside the oven is circulated, heated, and dried, which greatly increases the utilization rate of waste heat and improves environmental protection efficiency.

[0004] However, there are still some shortcomings in this patent. Although this patent can dry tobacco leaves, it can be seen from the drawings of this patent that this patent cannot quickly remove tobacco leaves during drying, resulting in slow replacement efficiency of tobacco leaves. Therefore, those skilled in the art provide an intensive flue-cured tobacco thermal cycle drying device to solve the problems raised in the above background technology. Utility Model Content
